Connections

Incorrect wiring may result in damage to the relay. Be sure to check model and part number before

connecting and energizing a particular relay.

NOTE

Be sure that the relay is hard-wired to earth ground with no smaller than 12

AWG copper wire attached to the ground terminal on the rear of the unit case.

When the relay is configured in a system with other devices, it is

recommended to use a separate lead to the ground bus from each unit..

Connections should be made with minimum wire size of 14 AWG except as noted for the ground wire.

Typical ac input and dc control connections are shown in Figures 4-7 and 4-8. The auxiliary output jumper

configuration schematic diagram is also shown in Figure 4-8. Relay internal connections are shown on the

back of the relay. Figure 4-9 shows a rear view of the relay and the connections.
